摘要

OBJECTIVES(1) quantify 12-month failures of restorations that were repaired or replaced at baseline; (2) test the hypothesis that no significant differences exist in failure percentages between repaired and replaced restorations after 12 months; (3) test the hypothesis that certain dentist’s, patient’s and restoration’s characteristics are significantly associated with the incidence of restoration failure.
